Referring to the drawings, the re'ife'ienoe ohzirscei i s used Lo Ldespiste the machine and the reference 'Character B the 'Cy'li'ndei' blockto he treated. The schine 'A Coinpiises :i has@ supported on legs 3].and having at one end 'a power drive and feed 3Q. Hinged et to fthelesse 30 is 'the plaie oi' 'hed 34- io which the cylinder YhloCk B isrigidly secured,

The bed 34, shown Iiisitienlsily in Fig'. '22 has n pe'iiphei'al liange35 and en erin 36 projecting' at en angle thei'eiroin prefeiealolyii'iteginl with he hed. The ontei` end 37 of the .fiiin 3G is enleigedfind machined and in it sie proi'ided two holes 38 and 39 for a, pnipeseto he described later. lio'jecin'g from the @it each side of the bed:ii-e iniegml plates 'and 4l, against the inner faces of which thebottom flange of the cylinder block to be treated is rigidly secured bybolts passing through holes in the plates 40 and 41 and engaging holesalready drilled in the cylinder block. In Order to locate the blockaccurately on the bed, the faces of the plates 40 and 41 are accuratelymachined into alignment. The embodiment shown is particularly adaptedfor Ford motors and the holes in the plates are so arranged that whenthe cylinder block is in alignment on the bed 34, they will alwayscoincide with certain holes already provided in the block for the boltsholding the lower half of the crank case in osition. The outer end ofthe block is bolted to the plate 40 and the inner end to the plate 41.

The hinges by which the bed 34 is joined to the base comprise angleplates 42 fixed to the base and carrying the hinge plate 43 and angleplates 46 bolted to the bed 34 in such a osition that they contact withthe hinge plates 43. A rod 47 inserted through the coinciding holes inthe plates 43 and 46 holds the two parts together and acts as a hingepin and can be easily removed when it is desired to shift the positionof the bed on the b-ase.

The hole 38 in the arm 36 is not threaded and is so located that itcoincides with the hole 48 (Figure 14) always provided in a Fordcylinder block for one of the bolts by which the water jacket (notshown) is secured to the block. A pin 49 passing through the hole 38 isthreaded into the hole 48 and clamps the block in place. The hole 39 isthreaded and so located that it does not coincide with a hole in thecylinder block so that the end of the bolt 50 (Figure 18) passingthrough the hole 39 bears against the block and by turning the bolt theblock is raised or lowered. The bolt 50 thus determines the position ofthe block relative to the bed while the bolt 49 holds the parts in thatposition.

Along the longitudinal edges of the base 30 are raised faces 51 whichare machined into absolute alignment. By these faces the variouspositions of the cylinder block are accurately determined. The underside of the bed 34 is similarly provided with raised faces 52. rlhefaces 52 are accurately machined and when the bed is in position, reston the faces 51 of the base. On the upper side of the bed 34 is formedan integral projection 53 the upper face of which is machined intoabsolute parallelism with the faces 52.

After the cylinder block has been mounted on the bed and bolted to theinner faces of the plates 4() and 41 a square or level is placed againstthe block flanges and rested on the projection The bolt 50 is now turnedto shift the block into the desired direction until it is exactly atright angles to the projection 53 and consequently to the faces 51 and`When this position has been reached the pin 49 is tightened to fix thebloclr in place. rEhe enlarged outer end of the p-in 49 is of suchlength that when the hed is swung on its hinges into the first position,as shown inFigs. 1 and 2, it bears against the hase and holds the bedfaces 52 right angles to the base. Since the cylinder block haspreviously been adjusted on the bed until it is at right angles to thebed faces it follows of course that it is now exactly parallel to thefaces 51 of the base.

In this position the bearings are robabbitted by pouring Babbitt metalonto the bearing surfaces. To insure accurate bearings a fixture 60 isemployed comprising a rod 61 of a diameter slightly smaller than that ofa. Ford crankshaft supported on the block by cross arms 62. On the rod61 at each side of each bearing are pinned rings 63 and at each bearinga plate 64 is bolted to the rod between each set of rings 63 for thepurpose to be described below. The arms 62 which are fixed to the rod 61hold it above the bearing surfaces 65 so as to provide a space for thebabbitt lining. (See Fig.

In order to guide the babbitt so that it will fill the space 66determined by the rings 63 at each end of the bearing surface 61, funnelblocks 67 are employed. These blocks are cut away on three sides toprovide the funnels 68, 69 and 70. Referring to Fig. 1 it will be notedthat these funnels are of different sizes corresponding to the sizes ofthe bearings of the cylinder block B. The funnel 68 will be used for thefront bearing the funnel 69 for the center bearing and the funnel 7()for the rear bearing. A knob 71 on each `block facilitates handling andmay be engaged by lifting tongs when the block is hot. Fig. 3 shows theposition o-f the various parts when ready for pouring the babbitt.

The plate 64 in addition to cooperating with the funnel blocks 67 alsofunctions to prevent the babbitt from contacting with half thecircumference of the rod 6l.. If this plate were not used and thebabbitt allowed to creep around the rod so as to partly enclose it therod could obviously not be removed without destroying the formedbearing. As shown in Figs. 1 and 3 the plates as well as the cross arms62 are firmly fixed to the rod thus insuring the formation of accuratebearings in each case.

The power drive and feed mechanism 32 is mounted on the face 54 of thebase which is parallel to the faces 51 and is operated by a shaft 190having loose and drive pulleys 101, adapted to be operated by anysuitable Source of power. On the shaft is a worm 102 Figure 8) whichmeshes with 'a Worm wheel 103 fixed b y screws 101 to a sleeve 105. Thesleeve has at one end a disk 106 here shown as integral therewith towhich disk is bolted a plate 107 by cap screws 108 having dovvel likeprojections 109 from the caps for the purpose pointed out below. Throughthe middle ot the plate 107 is breached a rectangular hole 110 whichreceives the squared portion 111 of a shaft 112 which extends throughthe sleeve 105. The worm and worm wheel are enclosed by a housing 113having at each side projecting flanges 111 and 115 which act as bearingstor the sleeve 105. As shown particularly in Fig. 8 the shat't 112 hasalso a threaded portion 116 which normally projects from the sleeve 105.The threaded portion 116 is somewhat longer than the squared portion 111for the reason to be pointed out later.

In certain uses of this machine it necessary that the shaft 112 movelongitudinally or feed as well as rotate. This 'function is olitainedlby the use of a split nut mechanism comprising a split nut 117, anannular guide plate 11S and a cover 110. rllhe split nut 117 is made upof two similar members 120, each including a senti-circular boss 121. Inthe adjacent Jfaces ot the members 120 at each side of the bosses 121are pockets to receive the ends of springs 123 by which the members 120are norn'ially held apart as shown in Fig. 9. Projeeting` from the outerface of each member 120 adjacent the center of the boss 121 is a pin121., the function of which will be pointed out later.

The guide plate 118 has an oval opening 125 in its center through whichthe bosses 121 and pins 124 project, recesses 126 being provided at eachend ot the oval to receive the pins. Screws 127 passing between themenibers 120 outside the springs 123 secure the guide plate to theflange of the housing. Collars 12S are slipped over the screws toseparate the guide plate from the tiange and prevent binding of themembers against reciprocation. Pockets 120 are provided in the adjacentfaces ot the members 120 in which the collars 128 will seat` when themembers are brought into contact. Hence the guide plate 118, by its ovalopening with the recesses 120, limits the separation ot the members 120.The inner taces ot the` bosses 121 are threaded so that when the members120 are brought together the threaded portion 116 ot' the shaft 112 isengaged. Inasmuch as the members 120 are held against longitudinalmovenient. it' the shaft 112 so engaged be rotated it must necessarilymove longitudinally. IVlhe collars 128 and the pockets 120 determine theapproach ot' the members to each other and thus prevent mutilation ofthe threads by too close engagement ot the bosses 121 and the shaft 112.

The cover 119 has a peripheral ange 130 which completely encloses theguide plate 11S. An annular groove 131 formed in the outer tac-e of theplate 118 receives the screws 1532 which project through the flange 130so that the cover is held in place but allowed a rotative movement whendesired. 'l`hrough the center ot the cover 119 is an opening 133 tor thebosses 121 and pins 124 ot' thc member 120.

The edges ot' the opening 133 have a double cam-like contour so formedthat when thc pins 1.24, which under pressure o't' the springs 123always bear against the edges, are at the diametrically opposite highpoints 186 they will lie in the recesses 126 of the guide plate 11S andthe bosses 121 will be ont ot engagement with the shat't 112. 1Vl1en,however, the cover is oscillated on the plate 118 by the handle 135 theboSSes are torced closer together until when the low parts 134 ot theedge bear against the pins the bosses are in mesh with the shaft and anyrotation thereot' causes it. to shitt longitudinally.

ln the base 30 and bed 34 are provided a number ot' holes by means ofwhich the bed can be fixed securely in position While certain operationsare performed. Referring particularly to Figs. 1 and 22 it will be notedthat there are in the base three sets ot such holes: an outer set in theouter face 51 and numbered 150, 151. 152 and 152i respectively. anintermediate set 154, 155. and 157 and a transverse set 158, 15S) and160. the holes 158 and 160 being in the taccs 51 and locating a line atright angles to the shat't 112. ln the bed 34 are two sets. the outerholes 1.61 162, 163, 164, 105, 166, 167 and 16S, and the inner holes un.17e, 171 and 17e.

rlhe position shown in Figs. 1 and 2 and referred to as the firstposition is that of the cylinder block when the main or crank shaftbearings are to be rebabbitted. It is also the position in which thecrank shaft is most easily assembled and the bearings t'or the camshat't and valve push rods are preterably reained.

After the bearings have been rebabbitted as described above. the rod (t1is removed and the bearings are subjected to a furtl'ier operation bywhich the exposed surface ot' the babbitt is made to conform accuratelyto the motor crank shat't. This may be done either by scraping thcsurface with a borer or rcamcr or by burning-in or running-in thebearings with the crank shaft, rl`he first, method is preferred becauseBabbitt metal being more or less porous. it leaves the grain ot themetal open so that the bearings will retain a certain amount ot oil tilmwhile bearings tinished by the second method. altho highlyv glazed andmuch harder, will not retain the. oil as well and will not wear as long.However both methods can he carried out hy this einleodinient of theinvention.

The first niethod is performed When the cylinder block is in theposition shown in Fig. 4 and referred to as the second position. Firstthere is bolted to the block a fixture 200 carrying' in alignment withthe hearings a boring har 201 haring a pluralitr ot cutters Q02. Thesecutters are einhedded in the har as at 203 in Fig. Y and are held inplace hy screws Q01. In order to adjust a cutter in the har a Q05provided Whirh. as is shown in detail in t3 and 7 a curved plate adaptedto hear cloeely against the har Q01. and haring' on its inner tace :iportion Q00 recessed to receive the outer end ofthe cutter and determinethe amount ot' projection. ln usine this it ie tiret applied With itsinner Ytace against the har and the porton 20G over the end of thecutter. The screw 2011 non' ooseuei. and the cut ter is pushed outagainst the jigA hy .sonic ineans inserted through the tiared opening.207 against the loutt oi the cutter. 'the cutter is thus quickly andaccuratclmt' azlgfizsted.

The boring har Q01 is fastened to the head 106 by an intermediatecmipling or union 208 which connecte the end ot the hoiiugj har to theshait 112 which projects treni the face ot the plate 10T. ln order topoi-:ition the boring har accirriately with reference to the otherparte` oic the motor, and partieularly iii order to insure that thecrank shaft hearings shall carry the ci'anl: shaft alisolutely parallelto the cani shaftT plates 209 (Figure project troni the hack ot' thefixture 200.

Should it lle desired to carri' out this scraping' operation hyreaniiiia'. a suitable fixture and reanier are substituted for thefixture 200 and the boring bar 201, the other arrangements being'unchanged.

The position shown in Fie'. S ot the drawings, referred to torconrenieiice as the third position, is that which `the cylinder hlocl;

With its supporting hed 34 occupies when the rebahhittcd inain hearingsare treated according to the second method, i. e., burnedin or run-in.In pericniningv this operation the cylinder crank shaft 225 is inount'edin place and driven hy the plate 10T through the dowel like projections109 which engage holt holes in the shaft lnange F226.

The hed is thus held inplace h3' triangularly arranged means haring au apex diiectly in lirontof the cylinder operated upon so that the block is held rigidly inalignment with the poner drive fri and. the cylinder is accuratelybored.

The boring har Q is tixed to the shi-itt 112 hy an); suitable connectionsuch as, 'tor example. the connection 20S shown in l" #i and hay; anenlarged intermediate p r tion 251 from which projects the cuttii edgeol' the hlade The lilade usual rectane'rhi r and is mounted in ai'ectanir pocket 2l hroaclicd thru the har. lh blade 252 haring acutting edge extentie l body portion 260 which bears against the innerend oi" the cutter blade In settingv the blade for cutting a micronieteris used and the blade is tiqed by means ot' the screw and the holdingscrew 261 so as to contact with the inner surt'ftce et the averagecylinder of the kind ot mot/ir operated upon. Should it he tound uponexamination that the cylinder to he bored is larger -or smaller than theaverage the projection of the blade is incre sed or diminished by meansof the screw i255, the lines 25S and 259 acting` as a micrometer tolguide such a change. Y The boring bar is preliminarily located in thecylinder to be bored by means ot tapered plugs Q75 shown in detail inlli 15 and 1G. These plugs con'iprise two ha 276 and 277 each havingl asenii-cylindrical recess so that when assembled as shown in the drawingsa cylindrical hole tor the boring bar is provided. On the block Ei'fi isprovided a tapered tin Q79 and on the bloifl; 27T are provided thetapered tins L80. 1" i blocks are held together by donels 381 and areaccurately ground so that the outer tuces ol the tins T) and 280 tornipart ol 'the tace of a cone whose center lies on the longitudinal axisot the hole 27S.

The plugs 275 are placed on the boringbar which is in the cylinder lo bebored and are then forced into each end et the cylinder as tar as theycan go. Thi;. by reason ot the accu 1ate machining ot tht` lslocls.positions the cutter bar at the renter ol' he cylinder.

Permanent guides 281 and ESQ are now employed, the Yformer at thebotte-ui ot the cylinder block and the latter at the toga. The guideQ81, shown in Fig. 2l. which has a row of holes 283 at each end. isslipped over the end of the boring har and bolted against the bottoniflanges ot' the cyliniler block. These flanges hare rows ot holesthrough Which the lower halt ot' the crank case, not shown, is bolted inplace and by providing the rows ot holes fl at each end of the guide, itis possibie to iind a eet tl'irouglrwhich the guide can he boiled to theblock.

The guide has a body plate 2511 which is bolted to the top ot thecylinder bloclr and in which is a hole 285 larger than the preliminaryplug Q75. so that when the guide Q82 is bolted into place it surroundsthe guide Projecting troni the plato .Q8-l is a bearing arm 286 by whirhthe t ter bar is supported. 1t will be not" an examination ot Fig. 1lthat when permanent guides are in position the preliminary plugs orguides ern en. 1 removable. that at the bottoni by reason ol" theopening :it the bottom ot' the cvlinder block. and that at the topbecause, the hear ing arm spaced from the upper side of the blot-lt. Theplugs are first pulled out of the cylinders and then separated into theblocks 276 and :277. The cutter bar when held by the plugs 275 could notbe ievolved but the permanent guides provide bearings in which the barcan be rotated and also advanced. the handle 135 ot' the cover lli)being thrown over so that the bosses 121 will engage the shaft, 112 andcause it to advance lrmgitudinally as well as to rotate.

The shaft 112 has, as shown in Fig. S. a threaded portion 116 and asquared portion lll, and is driven solely by the engagement ot the plate10T with the squared end. Obviously therefore if the split nut mechanismengages the shaft until it is so tar advanced that the squared portionprojects entirely it'rom the broached hole 110 the result will be thatthe shaft will no longer revolve. 1n view ot this fact the lengths ofthe portions 111 and 116 have been so determined that after the blade252 has passed conipleteliA through the cylinder being bored the squaredportion 111 projects entirely from the hole 11() and the operativeaction otl the machine ceases. Thus the boring is auto- .itieallycontrolled so that While the c vlin'- der being bored the operator canbusy himself elsewhere with the knowledge that the operation will ceasewhen the work is tinished.

The plugs or guides 275 shown in Figs. 15 and 16 are, as pointed outabove, absolutely symmetrical. Fig. 17 however shows the way in which acylinder' is often scored. llvhen a cylinder is scored, as shown in thatfigure. it is wasteful to remove the material equally all around andthus increase the cylinder diameter to the extent shown by the circle223i". .instead ot so doing the material within the circle may beremoved. vWhile this shifts the center of the cylinder slightly it doesnot aiiect its operation to any noticeable extent and on the other handit prolongs the lil'e of the cylinder. since many cylinders which couldnot be bored out by the old process can now be bored out. This operationcan only be performed if 'the center of the cutter bar be shifted and inorder to do so the plugs or guides Q75 are made ottset. in other wordsthe tins are machined not from the center of the cylindrical hole 278but trom another point. the desired distance away. The offset plugs arethen inserted in the cylinder with their center line shitted nearer thescored side of the cylinder and the center ot the cutter bar willnecessai-ily he equally shitted so that the material within the circle288 will he removed, by the rotating blade 252. The location of thecutter bar in the cylinder is determined by the plugs 275 and not by thepermanent guides QS and 28:2 which simply hold the bar in he positionwhich has been previously det termined for it by the plugs lbile oneembodiment onljvv of my inven tion has been shown and deL cribcd l amnot to be limited thcreb)v since il; obvious that others could be made1without departing' trom the spirit and scope oit r l Y invention as eetforth in the following;3 claims.
